ADMONISHMENTS
Important safety admonishments are used throughout this manual to warn of possible hazards to
persons or equipment. An admonishment identifies a possible hazard and then explains what may
happen if the hazard is not avoided. The admonishments — in the form of Dangers, Warnings,
and Cautions — must be followed at all times. These warnings are flagged by use of the
triangular safety icon (seen below), and are listed in descending order of severity of injury or
damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that will cause severe
personal injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe
personal injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause
minor personal injury or property damage if the hazard is not avoided.
SAFETY INFORMATION
Caution: A crated DSX bay may weigh as much as 318 kg. (700 pounds), depending on
its size and configuration. An adequately rated and secured block and tackle or
overhead hoist must be used while uncrating, positioning and securing each bay.
Caution: All DSX wiring and cabling should be connected with the system office battery
input off or disconnected at the office distribution panel.

1. GENERAL
1.01
This section describes ADC’s E1 Digital Signal Cross-Connect (DSX) System, which
serves as centralized termination, test access, cross-connect points and distribution frames for
digital equipment. DSX System components are available that work with the E1 bit rate and
signal level of 2.048 Mbps.
1.02
Signals from all digital equipment are maintained at an equal level at the DSX by a
number of methods which compensate for the various cable lengths. This allows for testing,
patching, and rearranging of equipment at the DSX without having to readjust signal levels.
1.03
ADC’s DSX Systems are suitable for both large and small offices, and customer
premises. Each can be designed and configured by the user or by ADC to meet the specific
requirements of the office in which it is to be located. Systems are modular and can be designed
to handle all cross-connect requirements in an office, or to supplement existing office crossconnect systems. DSX Systems can be expanded later by simply adding more DSX assemblies.
2. FUNCTIONAL DESCRIPTION
2.01
A DSX System consists of any number of individual DSX terminations to which
network elements are connected and cross connected. Each digital E1 circuit requires two DSX
terminations as shown in Figure 1-1. Each DSX termination consists of access points and two
cross-connect terminals. The circuit is completed by cross connecting the IN and OUT circuits,
either by jumpers at the cross-connect terminals or patch cords to the jacks.

1st Edition, Issue 1, October 1996
In Figure 1-2, network elements A, B, and C are connected to the DSX equipment
2.03
IN/OUT terminals of three different DSX jacks. Network elements A and C are then connected
together at the DSX by patch cords on the cross-connect terminals. The corresponding tracer
lamp terminals (TL) are also jumpered together. Cross-connected elements A and C can now be
identified, monitored and tested as follows:
•
Circuit Identification – Insertion of a functional or dummy plug into either of the two
DSX MON jacks causes the tracer lamps at each end of the corresponding cross-connect
jumper to flash for about thirty seconds and then remain lit. This gives a visual
indication of the equipment units that are jumpered together.
•
Bridged Testing – Test equipment patched into either of the MON jacks allows testing
without interrupting the signals between the A and C equipment.
•
Split-circuit Testing – Test equipment patched into an IN or OUT jack splits the A-to-C
equipment circuit for direct testing of either equipment unit.
In addition, patch cords can be used to split cross-connected network elements, and
2.04
connect either of the two elements to a third element. In Figure 1-2, network element C is
temporarily patched to network element B.
As shown in Figure 1-2, numerous testing and patch-around configurations are possible,
2.05
all of which are established permanently or temporarily at the centrally located DSX System. As
a result, many benefits can be immediately realized in the following areas:
Note: The Operation section of this Manual provides schematic diagrams and step-bystep procedures for most of the functions performed at the DSX.
A. Testing and Fault Isolation
By terminating all digital operational and test equipment at one central point (the DSX),
2.06
overall office equipment preventive and corrective maintenance can be performed at that
central location. Identification of existing or developing problems is readily accomplished at the
DSX by:
•
Bridged or intrusive testing at DSX jacks connected directly to network element inputs
and outputs.
•
Patching in spare equipment for suspected faulty units.
B. Interoffice Service Restoration
The loss of a major facility between two locations may isolate or greatly reduce the
2.07
service capability between the two sites. To temporarily restore partial communications between
these two sites, several circuits can be rerouted through a third site by simple patch arrangements
at the DSX Systems at the three sites. After the facility is repaired, these temporary patches are
easily removed and normal service between the two sites is restored.

ADCP-80-352
1st Edition, Issue 1, October 1996
C. Exchange Layout
The DSX makes it possible to add equipment to an exchange without major changes in
2.09
the exchange layout. Equipment is simply installed where space is available and then wired to
the DSX. Cross-connect jumpers on the DSX connect the equipment into the desired exchange
configuration.
D. Digital Switch Cutover
The DSX simplifies the cutover of a new digital switch. When a digital switch is
2.10
installed, it is terminated on the DSX. The existing cross connections serving the analog switch
are then replaced by temporary patch cords and new cross-connect jumpers are installed for
the digital switch. Cutover to the new switch is then completed by removing the temporary
patch cords.
E. Exchange Record Keeping
The DSX minimizes record keeping by providing large designation strips and cards for
2.11
labeling of connected equipment locations and other terminations. In addition, color-coded tracer
lamps are available to readily identify different types of equipment cross connected at the DSX.
3. SYSTEM COMPONENTS
All DSX circuits are available in various bay configurations, which include both
3.01
prewired and stand-alone modules. The DSX bays may also be provided with various types of
test equipment and signal sources, and are equipped with the necessary panels and hardware for
connecting and routing cables and wires between bays and bay lineups.
The following paragraphs briefly describe the bays, modules, and panels available for
3.02
designing a DSX System. System components are described in detail in ADC’s DSX Product
Catalogs.
A. High-Density Bays
Three types of high-density, DSX bays are available. All high-density bays are
3.03
preassembled and prewired, and may be ordered custom-built to meet specific exchange needs.
These bays do not require spacers between bays for cable management.
Standard High-Density Bays
Standard high-density bays are of various sizes and circuit capacity, with a 2.13 m (7.0
3.04
ft) bay containing as many as 832 DSX circuits. A varied selection of modules, panels, and test
equipment may be designed into these high-density bays and all cross connections are made at
the front. A typical standard high-density bay is shown in Figure 1-3.

Each bay provides three segregated DSX fields comprised of:
3.05
•
Input/Output Panels – These panels are located at the upper rear of the bay and provide
termination of equipment input/output circuits.
•
Cross-Connect Panels – These panels are located at the lower front of the bay, and
provide terminals for cross connecting all equipment terminated at the Input/Output
Panels.
•
Jack and LED Panels – These panels are located at the upper front of the bay and provide
Bantam jacks and associated LEDs for circuit tracing, monitoring, and testing of all
terminated office equipment.
These panels are all internally wired into individual DSX circuits, one of which is shown
3.06
in Figure 1-4.

Waterfall High-Density Bays
Waterfall bays are the same as the previously described standard high-density bays,
3.07
except that they are designed to distribute all equipment input/output cables across the rear of
each bay rather than down each side. This provides a more orderly cabling arrangement with no
space between bays.

Super High Density Bays
Super High Density Bays are of various sizes and capacities with a 2.13 m (7.0 ft) bay
3.08
containing as many as 1152 DSX circuits. A typical Super High Density Bay is shown in Figure
1-5. A typical Super High Density Maintenance Bay is shown in Figure 1-6. Each bay provides
three segregated DSX fields comprised of:
•
Input/Output Terminal Blocks – These terminal blocks are located at the upper rear of
the bay and provide terminations for equipment inputs and outputs.
•
Cross-Connect Terminal Blocks – These terminal blocks are also located at the rear of
the bay and provide terminals for cross connecting all office equipment terminated at the
Input/Output terminal blocks.
•
Jackfield Panels – These panels are located at the front of the bay and provide Bantam
jacks and associated LED indicators for circuit tracing, monitoring, and testing of all
terminated office equipment.

B. Skeleton Bays
The Skeleton Bay is designed to ease the expansion of the DSX by providing all cable
3.10
management before it is needed. Without the Skeleton Bay concept, as installed DSX line-ups
are expanded, DSX panels. Jumpers are often restricted from running in any direction since
jumper rings did not exist at unequipped panel positions. When jumpers are pulled too tight
across unequipped positions, feeding them into new rings is difficult, if not impossible. Jumpers
often cut across corners as they transition from vertical to horizontal wireways.
Page 1-8
© 1996, ADC Telecommunications, Inc.
ADCP-80-352
1st Edition, Issue 1, October 1996
The Skeleton Bay concept allows existing jumpers to remain undisturbed when adding
3.11
panels to the DSX, and jumper routing is not restricted in any direction since all wireways are
already established. Skeleton Bays are the recommended rack and cable distribution system for
use with DSX lineups. Figure 1-7 shows the components that are included with the Skeleton Bay.

C. Drop-In Bays
Drop-in Bays are also preassembled and prewired; however, they are comprised of any
3.12
of the various DSX modules and panels described in the following paragraphs. Input/output and
cross-connect terminals and corresponding patching jacks and indicators all reside on each DSX
assembly rather than in individually segregated fields across the bay. These bays may be shipped
with any number of DSX modules or panels installed, and as termination requirements increase,
additional modules can be “dropped in” in the office and wired into the existing bay. A 2.13 m
(7.0 ft) drop-in bay provides for termination of up to 924 circuits.
D. DSX Modules and Panels
Bantam jack DSX modules are available in various sizes and configurations and may
3.13
contain up to 90 individual DSX positions to which digital equipment may be terminated and
cross connected. The front and rear views of a typical 64-circuit module are shown in Figures
1-8 and 1-9.

A combination 120Ω/75Ω panel is available for terminating a mixture of E1 120Ω and
3.14
75Ω cables. Use of this panel should be limited to small office applications since large office
jumper management systems generally cannot support a mixture of coaxial and twisted-pair
cross-connects. It is recommended that no more than two bays of combination panels be used;
therefore future office growth should be seriously considered prior to installation.
Interbay Patching Modules
Interbay patching modules are jackfields used for patching between bays and lineups
3.15
when patch cord lengths become prohibitive. These modules allow use of a series of short patch
cords to connect any DSX terminations in the same or other DSX lineups. The point of signal
origin on a bay is patched to the closest interbay module and from there the signal is transmitted
via hardwired connections to other interbay modules in the bay lineup(s). The point of signal
destination is then patched to its closest interbay module to complete the circuit.
Interbay patching modules are available with Bantam jacks as shown in Figure 1-10.
3.16
This panel is equipped with busy indicators to show which jack circuits are in use at any time.

Cross-Aisle Panels
Cross-Aisle Panels are comprised of double-sided wire-wrap terminals, with one side
3.17
used to terminate tie cables to another lineup and the other side used to terminate cross-connect
wires. Cross-connects between lineups are completed by connecting short jumpers at each end of
the tie cables to the selected DSX circuits. This eliminates the need to place long overhead
jumpers. Cross-Aisle Panels are available in several configurations and circuit quantities, one of
which is shown in Figure 1-11.

Miscellaneous Jackfields
Various configurations of Bantam and Miscellaneous Jackfields are available for
3.18
providing direct access to test signals and equipment at the front of a DSX bay. Types of circuits
and signal sources that can be wired to various miscellaneous jackfields are:
•
Pseudo Random Pattern (QRSS on panel) Circuits
•
Interbay Trunk Circuits
•
Bridge Monitor and Bridging Repeater Circuits
•
Bridged Jacks
A typical miscellaneous jackfield is shown in Figure 1-12. Patch cords are used to
3.19
connect the various circuits from a miscellaneous jackfield to the DSX jack for the equipment to
be tested.

Repeaters
3.20 Various models of repeaters are available for regenerating low level digital
signals. These repeaters are contained on circuit cards and plug into a variety of chassis
and panels.
Dual Intraoffice Repeater
The Dual Intraoffice Repeater regenerates any standard E1 (2.048 Mbps) signal. Each
3.21
repeater consists of a pair of signal regenerators on a single printed circuit board. Depending on
the mode of operation required, the two regenerators may be configured to operate in the same
direction or in opposite directions.
An artificial line at the repeater input provides shaped line loss for an input signal level
3.22
of 0 to -27 dB relative to the Digital Distribution Frame signal level. The repeater output
provides the standard E1 signal level up to a distance of 165 m. (543 ft.). Selectable equalization
networks correct for the following distances over 120-ohm twisted-pair cable:
•
0 to 67 meters (0-to 220 ft.)
•
67 to 134 meters (220 to 440 feet)
•
134 to 200 meters (440 to 655 ft.)

Dual Bridging Repeater
The Dual Bridging Repeater shown in Figure 1-14 has two regenerators that, depending
3.24
upon the mode of operation, are configured to operate in the same direction or in opposite
directions. Each repeater output will provide the standard E1 level signal up to 45.72 m (150 ft.).
This repeater automatically compensates for a flat loss input signal level of -14 to -26 dB,
relating to the DSX/DDF level. Typically this type of repeater is used to temporarily reroute
service without service interruption.

PIX-DSX Miscellaneous Jackfields
PIX-DSX miscellaneous jackfields are available with various jack configurations.
3.40
Jackfields are 10.16 cm high and are available in widths of 58.4 and 48.26 cm (23 and 19
inches). Vertical cable rings on the front of each side of the jackfield provide for management of
cross-connect wires.
Types of circuits that can be wired to PIX-DSX miscellaneous jackfields are:
3.41
•
Pseudo Random Test Pattern circuits.
•
Bridging repeater circuits.
PIX-E1 Loop-back Interface Card (LBIC)
Each PIX-E1 Loopback Interface Card (LBIC) provides a high density, loopback/E1
3.42
termination. The LBIC also provides remote loopback capability for routine maintenance and
troubleshooting.
The LBIC operates at the standard E1 (2.048 Mbps) signal and is transparent to line
3.43
code, framing format, and Bipolar Violations (BPVs). The LBIC terminates the Network OUT
E1 line and regenerates the received signal to the Customer IN side. It has input sensitivity down
to 27 dB below a nominal E1 level (3 V peak). The LBIC recognizes In-Band Loopback codes in
-2
an environment with a bit error rate of up to 10 . Additional factory set In-Band Loopback codes
are also available. Figure 1-29 shows a typical PIX-E1 LBIC connection.
Note: In-band testing is intrusive.

When the LBIC loses its +5 V power, E1 signal from the Network OUT to Customer IN
3.44
experiences a momentary hit but recovers when the transmission path is switched to an on-board
un-regenerated signal path. The signal from Customer OUT to Network IN is not affected. When
power is restored or applied to the LBIC, the LBIC will default to normal mode operation,
regenerating the Network OUT signal to Customer IN.
PIX-E1 Cross-Aisle Repeater Circuit Cards
Each PIX-E1 cross-aisle repeater circuit card incorporates standard ADC Bantam jacks
3.45
with a E1 regenerator. The regenerator is located in the E1 circuit transmission path just before
the OUT jack as shown in the connection diagram in Figure 1-30. These repeaters are used to
regenerate the E1 signal at a DSX when the cross-connect distance exceeds 18 m (59 ft).

1. GENERAL
1.01
This section provides instructions for installing the DSX System. Included are
requirements and procedures for mounting, cabling and wiring modules and bays. It is
recommended that the entire section be read and understood before beginning installation. In
addition, complete installation instructions are provided in separate installation guides specific to
a particular chassis, panel, or module. Refer to the Related Manuals listing in the front of this
manual for the ADCP number corresponding to a specific installation manual.
2. EXCHANGE REQUIREMENTS
2.01
Details of conditions required to install the DSX System in a central exchange are
described in the Global DSX (E1) Planning and Engineering Manual, ADCP-80-351. A proper
installation can not be accomplished unless the site has been appropriately prepared in
accordance with the guidelines provided in the Planning and Engineering Manual. Additional
installation-related specifications are provided below.
A. Space and Floor Loading
2.02
The DSX System consists of various modules and panels mounted in one or more 48.26
cm (19 in) or 58.42 cm (23 in) equipment racks. The height of the racks may be 2.13 m (7 ft),
2.74 m (9 ft), or 3.5 m (11.5 ft). Approximate dimensions of the specific system purchased may
be ascertained by examination of the system design as shown in ADC’s DSX Product Catalogs.
A fully configured uncrated DSX bay may weigh up to 239 kg. (525 lb).

ADCP-80-352
1st Edition, Issue 1, October 1996
B. Environment
Operational
The DSX System will operate in any ambient temperature and humidity within the
2.03
following ranges:
•
Temperature: 0° C (+32° F) to +50° C (+122° F).
•
Humidity: 5% to 95% relative humidity without condensation.
Shipping and Storage
The DSX System can be shipped and stored in any ambient temperature and humidity
2.04
within the following ranges:
•
Temperature: –40° C (–40° F) to +70° C (+168° F).
•
Humidity: 5% to 95% relative humidity without condensation.
3. UNPACKING AND INSPECTION
Caution: A crated DSX bay may weigh as much as 318 kg. (700 pounds), depending on
its size and configuration. An adequately rated and secured block and tackle or
overhead hoist must be used while uncrating, positioning and securing each bay.
3.01
Remove all items from their shipping containers. Each chassis, module and panel
includes a separate package of parts. Verify that all parts on the packing slip have been received,
before shipping containers are discarded. If there are any damaged or missing parts, file a claim
with the commercial carrier and notify ADC as defined in Section 5 - General Information.
4. HARDWARE INSTALLATION
A. Bay Positioning and Mounting
4.01
Set each DSX bay in its assigned position according to the predefined layout. Secure
each bay to the floor and to adjacent bays or frames, using spacers between bays where specified
by system design. If overhead support is required, secure the bays to the overhead supports using
appropriate hardware. Refer to the Unequal Flange and Network Rack Installation Guide, ADCP80-345, for detailed installation instructions.
Page 2-2
© 1996, ADC Telecommunications, Inc.
ADCP-80-352
1st Edition, Issue 1, October 1996
B. Chassis, Module and Panel Positioning and Mounting
The unmounted package of parts contains mounting brackets, cable rings, designation
4.02
strips, installation drawing, etc. Place mounting brackets on the chassis, modules or panels and
install them in their assigned bay positions using 12-24 × 0.95 cm (0.375 in) mounting screws.
The remaining parts should then be placed as shown on the installation drawing.
Note: The 12-24 × 0.95 cm (0.375 in) mounting screws must be ordered separately.
Longer screws should not be used since they could damage cables on unequal flange
type racks.
ETSI/IEC Cabinet Installation
If you are installing an ADC DSX chassis into an existing ETSI-compatible cabinet, the
4.03
DSX chassis mounting brackets must be replaced with adapters to conform to the mounting hole
spacing of the ETSI cabinet. Refer to the Planning and Engineering Manual, ADCP-80-351, for
detailed adapter bracket specifications and ordering information.
5. SYSTEM WIRING AND CABLING
Wiring and cabling the DSX System into the office requires connection of office power
5.01
and ground, wiring of cross-aisle and interbay patching panels, cabling of network element
input/output circuits, and installation of all cross-connect jumpers. The following paragraphs
give procedures for installing all wiring and cabling, although all high-density bays and some
drop-in (module) bays are shipped with intrabay wiring already installed.
Caution: The system power input must be off or disconnected at the office distribution
panel, before connecting any DSX wiring or cabling.
A. Power Wiring
The DSX System operates on -48 Vdc filtered power, fused or breakered at the power
5.02
distribution panel. Approximate current requirements can be calculated based on a single
flashing Bantam LED draws .010 Amps.
The number of LEDs lit at any one time will depend on local patching and testing
5.03
procedures. It is recommended that individual DSX modules or panels be fused at the fuse panel
with a 0.5 Amp. fuse and connected to the fuse panel using 0.511 mm (24 AWG) solid copper
wire. Each high-density bay or fuse panel dedicated to an individual DSX bay serving only tracer
lamps and LEDs should be connected with 0.813 mm (20 AWG) solid copper wires to the power
supply and fused with a 3.0 Amp. fuse.

1st Edition, Issue 1, October 1996
B. High-Density Bays
Standard and waterfall high-density bays normally have battery and ground terminal
5.04
strips or blocks as shown in Figures 2-1 and 2-2. These terminals are located at the rear of the
bay to provide connection to the power and ground. Connect power and ground to the HighDensity DSX bays as follows.
1.
Connect –48 power to the –48 V terminals on the terminal strip/block.
2.
Connect –48 Vdc power ground to the B GND terminals on the terminal strip.
3.
Connect office frame ground to the C GND terminal. This is the recommended chassis
grounding procedure.
Note: The metal strap between the C GND (chassis ground) and S GND (shield ground)
terminals may be removed to isolate shield ground from chassis ground.

ADCP-80-352
1st Edition, Issue 1, October 1996
TB #1 through TB #3 and part of TB #4 are used to cross-connect the B CKTS, and the
5.15
remaining part of TB #4 along with TB #5, TB#6 and TB #7 are used to cross-connect the A
CKTS. The upper two rows of pins on these terminal blocks are internally wired to the output
jacks, and the lower two rows are internally wired to the input jacks.
TB #8 through TB #10 and part of TB #11 are used to terminate network element inputs
5.16
and the remaining part of TB #11 along with TB #10 through TB #15 are used to terminate
network element outputs. The upper two rows of pins on these terminal blocks are internally
wired to the corresponding A jacks, and the lower two rows are internally wired to the
corresponding B jacks.
The connection table in Figure 2-7 shows the same terminal block information in tabular
5.17
form. The table shows circuits 1 and 32 of the A CKTS and circuits 1 and 32 of the B CKTS.
Information on the remaining circuits can be interpolated from the table. The left half of the table
shows cross-connect terminal block information (TB #1 through TB #7) and the right half of the
table shows network element input/output terminal blocks (TB #8 through TB #15). For each
circuit, the table identifies the terminal block (TB), vertical row of pins and individual pins.
F. Cable Routing
DSX Systems are wired to the office equipment by means of cables at the back of each
5.18
bay. All cabling should be in accordance with the rules defined in the DSX System Design
section of the Global DSX (E1) Planning and Engineering Manual, ADCP-80-351.
If the cables are routed to the bay from above, cable attachment should start with the
5.19
lowest panels/modules and work up as shown in Figure 2-8. If the cables are coming from below,
cable attachment should begin at the top as shown in Figure 2-9.

All cables should be secured to brackets at the back of the bay (waterfall bays) or within
5.20
the duct (non-waterfall bays). The cable jacket should be stripped from an area past the last tie
on the cable bracket at a level about even with the wire-wrap pins to which the wires will be
connected. A six-inch service loop should be left before the cable is routed to the wire-wrap
terminals.
Network Elements Cabling
Using cables and wire-wrap tools, connect the network elements to their designated DSX
5.21
input/output circuits, maintenance panels and modules. Typical connections are defined in the
installation drawings accompanying the DSX equipment. Refer to Figure 2-7.
Terminate cabling for each network element input circuit to one pair of IN wire-wrap
5.22
terminals, and each output circuit to one pair of OUT wire-wrap terminals.
Cross-Aisle Panel Cabling
Cross-aisle tie cables between lineups in E1 systems should be interconnected in a
5.23
manner similar to Figure 2-10 or 2-11. Connect the tie cables to the terminals on the rear of the
cross-aisle panels as defined in the accompanying installation drawing. The OUT terminals of
the originating cross-aisle panel connect to the IN terminals of the terminating cross-aisle panel,
and the IN terminals of the originating cross-aisle panel connect to the OUT terminals of the
terminating cross-aisle panel.

G. Cross-Connect Wiring
Cross-connect jumpers should be routed as shown in Figures 2-16 and 2-17. Whenever a
5.26
cross connect changes direction, it should do so at a point where a ring, tray or fanning strip is
placed. This will allow the cross connect to be dressed neatly with no strain and without
interfering with any other portion of the bays. All cross-connect jumpers should use the
horizontal wireways between bays, and the vertical wireways within the bay. To prevent
unnecessary jumper buildup and congestion, all discontinued cross connects should be removed
from the DSX wireways.

Figure 2-17. Recommended Cross-Connect Wiring in Super High Density Bays
All cross-connects should be routed on the same horizontal wireway as the originating
5.27
point and then vertically in the wireway nearest the termination point. The cross-connects should
be threaded behind the horizontal wireways in all vertical ducts with approximately 12.7- to 17.8
cm (5- to 7-in) of slack. The slack should remain in the horizontal wireways when entering and
leaving the vertical duct.
The DSX drop-in modules with cross connects in place holds wire congestion to a
5.28
minimum if all recommendations are carefully followed. This not only simplifies installation,
but also provides for quick wire traceability and easy DSX expansion and maintenance.

1st Edition, Issue 1, October 1996
DSX Cross Connects
Using five-conductor 0.511 mm (24 AWG) jumpers, cross-connect DSX circuits as
5.29
shown in Figure 2-17. Terminal identification is as shown in the installation drawing
accompanying each module/panel (see Figure 2-8).
•
Connect the TL of the first termination to the TL of the second termination (green wire).
•
Connect the OUT of the first termination to the IN of the second termination (blue wire
and blue and white wire).
•
Connect the IN of the first termination to the OUT of the second termination (orange
wire and orange and white wire).
Remove any discontinued jumper by disconnecting each end and cutting off the bare
5.30
ends. Remove each end of the jumper from the vertical wireways, and carefully remove the
jumper from the horizontal wireway by pulling at either end. This method will allow the jumper
to be removed without snagging or placing undue strain on the remaining jumpers.

PROCEDURE 8
INTERBAY PATCHING BY MEANS OF SHORT PATCH CORDS
This procedure is used to patch between bay lineups or between distant bays in the same lineup,
without the use of long patch cords. Patching is accomplished with several short patch cords,
using the multipled, hardwired Interbay Patching Panels. A typical example is when a DSX
circuit in bay 2 is patched to a DSX circuit in bay 18 of the same lineup using Interbay (IB)
Patching circuit 3.
STEP
PROCEDURE
1
Install patch cord between DSX OUT jack in bay 2 to IB IN jack 3R on bay 4.
(Busy LEDs on jack 3 of IB panels in bays 8, 12,16 and 20 will light).
2
Install patch cord between IB OUT jack 3L on bay 16 to DSX IN jack in bay 18.
(Busy LEDs on jack 3 of IB panels in bays 8 and 12 will remain lit, LEDs on jack 3
of IB panels in bays 16 and 20 will be extinguished).
3
Install patch cord between DSX OUT jack in bay 18 to IB IN jack 3L on bay 16.
4
Install patch cord between IB OUT jack 3R on bay 4 to DSX IN jack on bay 2.
Note: Busy LEDs on jack 3 of IB panels on bays 8 and 12 will remain lit until patches
are removed. IB jack circuit 3 between bays 16 and 20 may be used for another patch.

1. GENERAL
1.01
This section provides information necessary to maintain the DSX System. Maintenance
requirements are minimal, consisting mostly of periodic cleaning and tracer lamp replacement.
2. PREVENTIVE MAINTENANCE
2.01
Systems should be cleaned during routine network element maintenance. Accumulated
dust and film should be removed using a vacuum cleaner and clean soft brushes and cloths. Care
must be taken to prevent dust and dirt from getting into panel jacks.
3. CORRECTIVE MAINTENANCE
3.01
DSX corrective maintenance consists of:
•
Replacement of burned out fuses and tracer lamps.
•
Replacement of Bantam jacks.
•
Replacement of circuit cards and octapaks.
•
Inspection and repair of wiring and connections.
3.02
For any repairs other than described in this section, refer to the General Information
section in this manual. If call is placed after hours or on a holiday or weekend, an answering
device will take the message and alert service personnel for call-back the following business day.

ADCP-80-352
1st Edition, Issue 1, October 1996
A. Troubleshooting
Troubleshooting of the DSX System consists of visual inspection and continuity testing.
3.03
Cross-connections can be quickly checked by bridging them with patch cords to the
corresponding IN and OUT jacks. Refer to the Maintenance section of ADCP-80-311 for specific
fault isolation processes for the PIX-E1 Repeater Shelf.
B. Tracer Lamp Replacement
Burned out tracer lamps are replaced at the front of the DSX bay. Lamps are removed by
3.04
pulling them from the panel sockets. No special tools are required. Replacement lamps must be
inserted with the negative (–) terminal up.
C. Fuse Replacement
Burned out fuses are replaced at the front of the fuse panel. Fuses are removed by pulling
3.05
them from the panel sockets and installed by pressing them into the panel sockets. No special
tools are required.
Caution: A replacement fuse must have exactly the same current rating as the fuse being
replaced.
D. Jack Replacement
3.06
Bantam jacks can be replaced at the front of the bay. Use of ADC’s jack repair kit is
recommended to support the jack panel during jack replacement. The jack repair kit consists of
two panel supporting brackets, five DSX jacks, a Phillips screwdriver, and the necessary
mounting screws. If this kit is not used, or if the jack panel is not mounted by screws at the front
of the bay, another means of panel support must be provided. Proceed as follows to replace a
DSX jack.
Caution: The –48 Vdc power must be turned off or disconnected from the bay/panel
during jack replacement.
1.
The support brackets included with the jack repair kit include two sets each of three
pieces identified in Figure 4-1.
Depending on how the front panel assembly attaches to the DSX module either brackets
A & B will be used or A & C will be used. If the mounting screws holding the front
panel are attached from the front, use brackets A & B. If the mounting screws holding
the front panel attach from the side, brackets A & C should be used. See Figure 4-2.
